IMPROVEMENT IN DIES FOR WELDING CHAIN-LINKS. I

Specification forming part of Letters Patent No. 188,545, dated March 20, 1877; application filed October 18, 1875.

To all whom it may concern:

Be it known that we, J AGOB SOHINNELLER,

of Pittsburg, in the county of Allegheny and .and State of West Virginia, have invented a new and useful Improvement in Dies for Link- Welding Machines and we do hereby declare that the following is afull and exact descrip tion thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our inventionrelates to an improvement in dies for link-weldin g machines, and consists in so constructingthe cavity in the dies with relation to the line of parting that the fin formed at the line of said parting shall be Worked into the body of the link by turning it (the link) so as to bring the-fin incontact with the Walls of the cavity of the dies distant from the line of parting.

To enable others skilled in the art to make and use our invention, we will proceed to describe its constructionand operation.

In the accompanying drawings, which form part of our specification, Figure 1 is an end view of the dies when closed together. Fig. 2 is a vertical section of the same at line 3 of Fig. 1, representing a section of a link in the gether, as represented in Fig. 1, the line of parting at D'will be distant from the center or axis of the cavity, as indicated by the line .0. In other respects the dies are of ordinary construction, and are operated in the usual manner, excepting that the link is turned in the die, so that the fin which is formed at the line, D, of parting will be brought below said line of parting, whereby such fin will be brought in contact with the solid portion of the female die, and be forced into the body of the link, thereby Welding a link free from fins or ragged projections but the skilled mechanic will readily understand the line, D, of parting of the dies may bearranged at different points and the sameresult accomplished, the gist of our invention being so parting the dies that the fin-formed at the line of parting may be worked into the body of the link by turning it in the dies, as herein described.

Having thus described our improvement, what we claim as of our invention is The improved die for Welding chain-links, consisting of the parts A B, inclosing curved space 0, the lines of parting of the parts out side and inside of the curved space being distaut from, and respectively on opposite sides of, a plane passing through the center of said space, whereby the fin is worked into the body of the link by turningit in said die, substantially as herein described.
